[Q] Batt consumption after OTA update

[omricn]

Did anyone notice a change in battery consumption after the ota update?
Before the update I was getting to 97 percent after about 3 hours of the phone in idle - almost no use at all, no WiFi.
now It got to 94 percent with the same usage apart from 3 photos taken, could be that i'm just too harsh about it.. but still - wanted to check if anyone noticed anything.

edit: also I forgot to mention that I added the "mail" widget to one of the home screens, could be the power taker?

Probably the mail widget and the picture shooting (takes much ressources).
I haven't noticed any increased battery consumption, but it is probably to soon to tell.

Also forgot to mention I added two 'folder organizer' widgets , two folders which contain apps and games.
tomorrow I'll start off by removing them + the email widget and see if there is a difference.

are u really lookin' after for a 3% change in a 3h time ? maaan ... this could be a simple measure problem ... dont it take it too serious. if ya want to test it, maki it at least 10-20h run in standby (airplane mode on) ... it doesn't that accurate.

Yeh yeh I know I know I'm exaggerating.. I'm just becoming insane when it comes to battery life for some reason.. guess it's still the HD2's influence
It shouldn't bother me that much as it is.. I have a charger in my car plus I'm almost never gone more than 9 hours from home, which should be more than enough for the batt to last.. call me crazy it just occupies my mind

Update: strangest thing.... I just checked the phone, didnt turn the screen on since exactly one hour ago, batt was at 83 percent... that's about 9 percent in one hour!!!
removed the folder organizer folders, rebooted the phone, and suddenly received sms messages I should have received last night

now that's becoming something I should put my eye on.......

Update -

Well after another hour, phone only dropped 1 percent, i'll try to isolate the problem by adding the folder organizer widgets back and check in in one hour to see what the batt has to say..
If it'll drop 1-2 percent I guess there was some glitch causing the phone to not get calls\sms's and drop the batt usage about 10% in one hour..

Another thing I'm going to do is let it drain until it turns itself off and then fully charge it, I'v heard you should do that like 5 times when getting a new phone.

Update - 1 percent after another hour + folder organizer folders.. so, guess it was some major batt\radio glitch since last night until i rebooted today (phone was on charge all night)

I noticed that the setting 'Best WiFi performance' adds a serious battery drain when enabled after installing the FOTA, I was loosing 8-9% an hour compared to 3-4% before the update. Disabling this brought me back to 2-3% an hour. I still have a way better WiFi-connectivity compared to before the FOTA with this setting disabled.

 

[omricn]

I actually never checked that option but yeh I get your point, all is ok now I'll update if anything weird will happen, i'm getting 1-2% an hour

Thanks a lot. Overlooked the Menu button step. ;-)

I charged mine up the night before last and have used it for internet, Angry Birds, whilst waiting for my clients and a lot of texting and about 10 mins of calls. This morning It's at 60% as I post this. I've noticed a huge difference since the upgrade and the phone is nowhere near as hot since the upgrade either.

It was a glitch 100%..
yesterday I let the phone drain itself (1day 7 hours - after the incident with the battery gone down 20 percent in 2 hours) then I fully charged it, turned it on last night before went to sleep, phone has been on since last night approx' 12 hours now - gone to 97 percent!! this is awesome!! I'm gonna' let it drain again a couple more times and this all over again

Battery lasts for approx 11-13 hours. Loosing 8-10% each hour with no usage at all.
It is updated. Reset to factory defaults. No extra apps installed. Just gmail, htc hub sync, wifi and that kind of stuff. No friends stream or Facebook or twitter.
What should I do? This is totally unacceptable.
Anyone tried to send it to service for fix?

first of all let the battery drain itself and let the phone shut down on its own, then fully charge the battery while the phone is off, do this for 3-4 times it will increase the battery's life span and charge time.
also check for the "best WIFI performance" as described in my post above, if it's checked uncheck it.
use auto screen brightness.
most important of all and may be causing your issue - check the stats of your charger, the charger I got with my sensation is imho faulty, it makes electricity noises, so I went back to my old HD2 one - perfect - the most important thing to check in your charger is the output voltages - it has to read 5v---1a - nothing different.

use auto screen brightness.

I think its better not to use auto screen brightness but use a fixed setting (maybe at around 25-30% brightness level). The reason being, the processor will have to be worked upon constantly to find the optimum brightness level and that would consume power!

Personally I believe the process of identifying the lighting and adapting to it doesn't take much effort from the processor, and based on my phone - the screen does consume energy but it will last 48 hours with the auto brightness setting on so why not use it? it's one of the good options we have in our phones and i really like it that when i go outside to the sun it'll increase the brightness in a millisecond.
the guy from the post above that's getting 10 hours of usage has a problem that I don't believe has something to do with his screen brightness unless he keeps the screen turned on all the time....

I updated to 1.35.xxx.x in the morning and after that the battery meter has only gone down by about 20% in the last 7 hours or so! The phone was off charge in the morning and I downloaded the update over my 2G connection. I also put on a live wallpaper just for fun! No calls made/received but few texts only. No games played. Surfed a little bit on internet (maybe 10 mins).

I'm liking it
